What version of the Codex App are you using (From “About Codex” dialog)?

26.426.12240

What subscription do you have?

Pro

What platform is your computer?

Win11

What issue are you seeing?

Codex begins freezing upon chats with multiple image generations. I am working on a project and using the /image generation skill a lot. Once the chat reaches around 10-20+ images, the chat consistently freezes for about 30s - 1 minute upon sending a new message, or receiving a message from codex. My solution has been to archive the chats after this becomes too much of an issue and begin a new one.

What steps can reproduce the bug?

Chat with around 10+ generated image assets, send a new message or receive a new message.

What is the expected behavior?

30s - 1 minute freeze upon chat with many images created via /image generation skill.

extent analysis

TL;DR

The issue can be mitigated by archiving chats with a large number of generated images and starting a new chat.

Guidance

  • The freezing issue seems to be related to the number of generated images in a chat, suggesting a potential performance or resource limitation.
  • To verify, try limiting the number of image generations in a single chat and observe if the freezing issue persists.
  • Consider archiving chats regularly to prevent the issue, as the user has already found this to be a temporary workaround.
  • If the issue is critical, consider reaching out to the Codex App support team for further assistance, as the problem may be specific to the Pro subscription or version 26.426.12240.

Notes

The exact cause of the freezing issue is unclear, and it may be related to the specific version of the Codex App, the Pro subscription, or the Windows 11 platform.

Recommendation

Apply workaround: Archive chats with a large number of generated images and start a new chat, as this has been found to temporarily resolve the issue.
